Phonegap contact sort order on ios

Does anyone know how to sort the contact data that phonegap liberates from iOS to javascript. The order at the moment is nothing to do with alphabetical sorting. I want to sort on last name.

Here is my contact code:

function init_contacts() {
     var fields = [ "name","phoneNumbers"];
     navigator.service.contacts.find(fields, contactSuccess, contactError, '');
}
function contactSuccess(contacts) {
    for (n = 0; n < contacts.length; n++) {
        if (contacts[n].phoneNumbers) {
            for (m = 0; m < contacts[n].phoneNumbers.length; m++) {
                addToMyContacts(contacts[n].name.formatted, contacts[n].phoneNumbers[m].value);
                console.log('Found ' + contacts[n].name.formatted + ' ' + contacts[n].phoneNumbers[m].value);
            }
        }
}
$("#my_contacts").listview("refresh"); 
};

function contactError() {
    navigator.notification.alerter('contactError!');
};

You can do this sort by hand in Javascript.

var cSort = function(a, b) {
  var aName = a.lastName + ' ' + a.firstName;
  var bName = b.lastName + ' ' + b.firstName;
  return aName < bName ? -1 : (aName == bName ? 0 : 1);
};

function contactSuccess(contacts) {
  contacts = contacts.sort(cSort);
  ...
};

I am using this method, which is far more efficient (compared to the accepted answer)

var cSort=function(a,b){ 
        var an=a.name.formatted.toUpperCase();
        var bn=b.name.formatted.toUpperCase();
        return (an<bn)?-1:(an==bn)?0:1;
    };

function contactSuccess(contacts) {
  contacts = contacts.sort(cSort);
  ...
};
  1. Contact.name.formatted is more consistent across platforms
  2. All names starting with the same letter will be grouped together irregardless of the case. (you can also try it to see).

For more fun and cleaner code you may consider using lodash

contacts = _.sortBy(contacts, ['last_name', 'first_name']);

sorting in js

function sortByitemName(a, b) { var x = a.displayName.toLowerCase(); var y = b.displayName.toLowerCase(); return ((x < y) ? -1 : ((x > y) ? 1 : 0)); }

function onSuccess(contacts) {

contacts.sort(sortByitemName);

 }
